rift is better than vive(4 ED anyway) and almost x2 cheaper. it isn't even a competition anymore.
also, if rift is still too much there's an even better ED VR HMD - Pimax 4k
Except the Pimax is incapable of positional tracking... which makes it kinda obsolete. Sure it's not bad for basic stereoscopic 3D with tracking.. but it isn't VR per se.
The next big players with their HMD's coming out Soon(tm) will shake things up I think. The inside-out tracking will make a huge difference to the ease of setup, but how well it's going to work remains to be seen.
